WARPING-MACHINE Specification of Letters Patent.

Patented Oct. 1 5,- 1907.

Application fired August 17,1906. serai No. 330,950.

To all 'whom it 'may concern:

Be it known that I, CHARLES H. KNAPP, a citizen of i the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented a certain new and useful Improvement in warping-Wlachines, of which the following is a specification.

The invention relates to machines for winding warpthreads upon a beam or spools, and more particularly to means for starting, stopping, and controlling the speed of such machines.

The object of the invention is to provide means conveniently located whereby the machine can be easily and quickly started or stopped and its speed increased or diminished at will, and which shall be simple in construction, positive in operation, and quickly responsive to the touch of the operator.

The invention consists in certain novel features, arrangements of parts and details of construction by which the above objects are attained, to be hereinafter described and pointed out in the claims.

The accompanying drawings form a part of this speciication and show the invention as it has been carried out in practice.

Figure 1 is a side view of a machine embodying my invention and showing only so much of the warping mechanism as is necessary to understand the relation of the present improvements thereto. Fig. 2 is a corresponding plan view. Fig. 3 is a rear view, and Fig. 4 a front view of the same. Fig. 5 is a plan view of the foot-levers for operating the controlling mechanism. Figs. 6 and 7 are elevations of the slide and latch forming part of such mechanism. Fig. 8 is a side view of the latch alone, and Fig. 9 is an end view of the same. Fig. l0 is an elevation of a portion of the controlling mechanism. Fig. ll is an elevation of certain parts of the same on a larger scale, and Fig. 12 is an elevation showing a detail of the same. Fig. 13 is a face view of a portion of the sprocket-chain employed in the controlling mechanism, and Fig. 14 is a side view of the same. Fig. l5 is a perspective detail of the slide, its latch, and the coperating pin,

Similar letters of reference indicate the same parts in all the figures.

The general construction of the machine in respect to the winding mechanism is similar to that shown in a patent to me dated Jan. 5, 1904, No. 748,750, and need not be specifically described. The present invention relates, as before stated, more especially to the controlling means.

A is the main shaft driven by a belt, not shown, running on a pulley A1, supported in bearings B1 B1 in the side-frames B B of the machine and arranged to be moved longitudinally therein by means to be described; the end opposite the pulley carries a friction-disk or face-plate A2 thus moved into and out of frictional contact with a horizontal friction-wheel Cl splined on a vertical shaft C journaled in a portion B2 of the frame and carrying at its upper end a beveled gear-wheel, not shown, inclosed in a casing B3, through which rotary motion is imparted to the beam or spools, not shown, by mechanism similar to that shown in the patent referred to above.

The shaft'A revolves continuously and the winding mechanism is started by moving the shait and faceplate longitudinally into strong frictional engagement with the friction wheel C1; it is stopped by moving the shaft and face-plate out of such engagement; and the speed is controlled by the radial movement of the friction-wheel C toward or from the center of the faceplate.

The friction-wheel has an annularly grooved sleeve C2 in which are engaged the arms of a fork D1 on a hollow slide D arranged to be moved vertically on a guiderod D2, and connected by a link D3 to one end of a lever DJK fulcrumed at d to a portion of the frame. The other 7 5 end of the lever carries a length of segmental gear D5 in mesh with a pinion El on a sleeve E2 mounted to revolve on an outwardly projecting stud B4 firmly fixed to the side-frame B.

By means of a hand-wheel E3 on the sleeve E2 the 80 latter with its pinion may be rotated by hand and the lever D4 swung on its pivot d to raise or lower the friction-wheel G1 and thus increase or lessen the rate of revolution of the shaft C and its connections, In order that the sleeve E2 may be revolved in either direction 85 and the machine started, stopped, and controlled without thus grasping the hand-wheel, the present improvement provides a system of levers and connected mechanism for performing these operations by the pressure of the foot of the operator or attendant, applied at the front, rear, or working-side of the machine in addition to the hand-wheel, thus permitting instant control from various positions while-the hands of the operator may be otherwise employed.

A3 is a sprocket-wheel on the main-shaft and F1 F2 95 are sprocket-wheels mounted on studs B5 B6, both at the same height within the frame B and in the same vertical plane. A sprocket-chain F running on the sprocket-wheel A3 is led by means of idlers G1, G2 and G3, to and partially around the sprocket-wheels Fl F2, the upper limb of the chain passing under the wheel F1 and over the wheel F2 causing them to revolve continuously in opposite directions. Each carries a friction-drum, marked F3 and F4 respectively, and above the drums is a swinging friction-wheel J1 on a short 105 shaft J carried in a fork J 2 on an L-shaped lever J3 ulcrumed on the frame B at j so that by swinging the lever J 3 the wheel or drum J l carried thereby may be made to Contact with one or the other of the drums F3 F4 and thus cause the short shaft J to rotate in either 110 direction as desired. On this short shaft outside the frame B is a sprocket-wheel J4 on which runs a sprocketchain J5 in mesh with a sprocket-wheel E4 on the sleeve E2 and the latter may thus be caused correspondingly to revolve in either direction inducing through1 the lever D1 the desired change oi speed.

Below the free horizontal arm of the lever' .l5 are two short foot-lovers H1 H2 both fulcrumed on the same stud 7i near the floor, and each has a link, marked respectively H2 Hu1 connected to the end of the free arm of the lever' J11 but extending thereto from opposite sides of the fulcrum h. The short foot-levers H1 H2 terminate in foot-plates H5 H5 at the rear of themachine and each carries a foot-plate H5 extending to the side of the machine. On the inner ends are overhung portions H7 H2 adapted to be struck from below by the ends of the long foot-levers K1 K2 respectively which are fulcrumed at 7c and extend to the front of the machine where they terminate in foot-plates K5. Thus connected the lever J 2 may be swung to bring its friction-Wheel J1 into Contact with either of the friction-drums F3 F4 by the foot of the operator applied to the foot-plates H5 H5 at the rear of the machine, or H6 HG at the side, or K2 K3 at the front.

The machine is stopped and started by the movements of a vertical slide L through lever connections to the main-shaft A. The slide carries a pin L1 engaged in a slot Z in the long arm L2 of a bell-crank lever fulcrumedwithin the frame at the rear; the short arm L3 is connected through an adjustable link L4 with an arm L5 on a rock-shaft L5 extending to the iront of the machine where it carries a forked arm L7 partially inclosing a sleeve A4 on the main-shaft and receiving pins A5 on such sleeve, the latter being held longitudinally between collars A5 A on the shalt so that the rising movement of the slide L moves the Yface-plate A2 toward the friction-wheel G1 to start the machine, anda reverse movement draws the face-plate from the friction-wheel and stops the machine.

The rising and sinking movements of the slide L are induced by the engagement of a pin N on an arm N1 attached to the sleeve E2, with the jaws L8 at the upper end ofthe slide, The latter is held in the elevated position by the vertical latch M resting at the lower end on the lug B5 on the frame and is released by the action of the pin N upon the upper end or head M1 of the latch in the act of entering the jaws L2. VThe latch is pivoted at m and its head is beveled so that the action of the pin N swings the latch against the force of a spring M2 sufficiently to disengage its lower end from the lug B5, conditioning the slide to descend with the further downward movement of the 'arm N1. The forked arm L7 is loosely mounted on the rock-shaft L6 and is moved by the latter through an arm Lg thereon, connected to a lug L10 on the forked arm by an expansion spring L11 serving to soften the movement and hold the friction-disk or face-plate A2 yieldingly to the friction-wheel C1.

From the above it will be evident that when'the sleeve E2is actuated through the operation of the swinging vfriction drum that the pin N is brought around so as to engage the catch M and release the slide L at the same time that the friction wheel C is brought to the center of the friction disk A2. The depression of a foot-lever throws the friction wheel J 7 into contact with the friction-drum F4 and through the sprocket-chain J5 and sprocket-wheel E4 revolves the sleeve E2 and causes the pin N to enter the jaws L8 and swing the latch M on its pivot m to release the slide L which by the further movement of the pin N on the arm i 7 is forced downward and carrying with it the long arm of the bell-crank lever L2. From the short arm L5 of this lever extends an adjustable link L4, above described, which through the -arm L5 partially rotates the'shait L11 and by means of the forked-arm L7 and pin A5 the shaft A and its friction-disk A2 is moved endwise to bring the latter into frictional contact with the friction-wheel C. The lifting of the slide by the rengagement of the pin N with the jaws Lf1 reverses the movement, throws the friction wheel C to or near the center of the friction disk A2 and at the saine time moves the shaft A and disk A2 axially out of contact with the friction-wheel C4 Lugs B5 and B7 on the framing, one at each end of the slot b in which the shaft J swings, are so shaped and located as to be struck by spur-links J 5 in the chain J 5 and limit the extent of motion of the `friction-wheel C1 by automatically throwing the friction-wheel J1 out of contact with its driver F 3 or F4.

Thus arranged the machine may be started, stopped and controlled by the hand-wheel E2 or by the foot of the attendant on the foot-plates; a light touch of the foot is sufficient to induce a slight change in speed, and as the friction-wheel J1 tends naturally to ainiddle position between the friction-drums F3 and F4, the parts automatically maintain their relative positions and the machine continues to run at that speed until again changed or stopped. The jaws L8 of the slide L are engaged by the pin N of the arm N1 through only a short arc of its circumferential sweep, suilicient to operate the slide in stopping and starting, during the remainder of its sweep the arm N1 swings idly with the sleeve E2 as the latter is partially rotated to vary the speed. Continued pressure on either of one set of footplates stops the machine, while similar action upon either of the other set starts it again.

The spur-links J 5 are so set as to engage the lugs B5 B7 and reverse the movement before the segment D5 has traveled in either direction out of mesh with the pinion E1; and the arm N1 is so located relatively to the pinion E1 as to engage the jaws of thelslide L and stop the machine at the time when the friction-wheel C1 is at its nearest approach to the center of the disk A2 and the speed correspondingly reduced. This is of course the starting position also.

Modifications may be made in the forms and proportions of the parts. The construction and arrangement of the foot-levers may be varied to present their footplates at other points than here shown, and a greater or less number of such operative points may be provided.
